Apparently we have been trying to return to the moon for the last 30 to 40 years and I didn't even know it. It was recently discovered that there may be ice within permanently shadowed regions of the lunar surface, potentially providing a source of water, oxygen, and rocket propellant. Harvesting these and other resources may help to transform the moon into a training and testing site as well as a jumping-off point for further space exploration.

An enlightening read that cover the moon's past and future.
